129: Improving and reducing biases with a novel theory
Henning Hoeber discusses a new tool for rock physics in his recent paper published in September's The Leading Edge.
In this episode, Henning explains the theory of omitted variable bias (OVB) and its connection to rock physics, why OVB hasn't appeared before in the geoscience literature, how OVB helps geophysicists understand biases in models, the real-world implications for improving a bias model, and how he will apply OVB to his future research.
